GEORGE HAYES, OF NEV YORK, N. Y.

WHEEL FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 610,743, datedSeptember 13, 1898.

Application filed July 31, 1897 To @ZZ whom t may concern:

Be it known that I, GEORGE HAYES, a citizen of the United States, and aresident of the city, county, and State of New York, have invented a newand useful Improvement in lYheels for Bicycles and other Vehicles, ofwhich the following is a speciiication.

My improvement relates to the center portion of the wheel, and has forits object the securing of elasticity and resiliency at that pointinstead of at the rim, thereby enabling pneumatic tires to be dispensedwith and my improvement consists in constructing the wheel-center withan axle-hub formed substantially as usual and disposed at a suitabledistance therefrom, an encircling spoke-nave, the two connected bycertain springs, each of which is formed with an eccentric coil towardand at one end, while the other end eX- tends more or less straight ortangentially thereto, the two ends being secured one to the axle-hub andthe other to the spoke-nave.

It further consists of such devices and combinations of devices ashereinafter more fully described and pointed out, reference being had tothe accompanying drawings,in which- Figure l is an edgewise view of oneof the springs used in the central part of the wheel. Fig. 2 is across-section of the axle-hub, showing inside face of one of thehub-flanges, inside face of one of the cheeks of the spokenave,and setof springs connecting resiliently the axle-hub and spoke-nave, withcross-rods used as braces and means for securing the springs. Fig. 3 isa sectional view of the wheel-center on line w fr of Fig. 2. A dottedline y .c in this ligure gives the section-plane of Fig. 2. Fig. 4f isan edgewise view of a spring analogous to that of Fig. l, but in twoparts, terminals overlapping. Fig. 5 is a view of the hub-center similarto that of Fig. 2, but with springs reversed and in greater number.Figs. G and '7 are edgewise views of springs, which illustratemodifications or variations permissible in form and arrangement. Fig. 8is a view of the hub-center analogous to Figs. 2 'and 5, illustrating amodication in arrangement of springs.

On the drawings, A indicates the springs used in the wheel-center andwhich are the distinctive feature of this invention. They may be made ofany shape in cross-section,

Serial No. 646,681, (No model.)

but preferably ilat. f They also may be used in any desired number andof any suitable width and thickness, also of any suitable material. Theyalso may be made of one piece, as in Fig. l, or in two parts, as in Fig.4t, or each half may be used singly. The springs are formed as eccentriccoils, each coil with tangential extension.

B indicates the axle-hub. This may be of any desired style, butpreferably such' as usual for bicycles, each being supplied with flangesB', forming part of the hub, or threaded or otherwise secured thereto.

C indicates the cheeks or end disks of the spoke-nave, which is separateand distinct from the axle-hub. The cheeks are formed as rings or diskswith hollow center and encircle the axle-hub.- The two cheeks are heldat the proper distance apart by cross-rods C or pillars, which alsoserve as braces. The interior ends of the spokes of the wheel aresecured to the spoke-nave near the peripheral edge ot the cheeks.

At D are arranged cross-rods or pillars eX- tending between and securedto the flanges B/ of the axle-hub. The springs have their terminalsinside the coils secured to the crossrods D of the axle-hub when usedanalogous to arrangement of Figs. 1, 2, and 3, or secured to cross-rodsO, while at another point or terminal they are secured to a cross-rod Cof the spoke-nave, and when used analogous to arrangement of Fig. 5their securing-points are reversed.

The action sought by the use of springs of the character and arrangementherein described and shown in the drawings is a combination of vibratoryand oscillatory motion, cushioning between axle-hub and spoke-nave withquick resiliency as against pressure or shock.

In Fig. 3 two sets of the springs are used,one at each end of the hub 5but dotted lines at E serve to show how one set of the springs may beused, their width taking up nearly the entire width between the hub-anges The wheel-center may be inclosed and the springs completelysecured against dust, dirt, dac., if desired.

At G a reinforcement is shown. Itis of spring metal and intended to easethe motion in case of excessive shock. Other reinforce-'- IOO I mentsmay be added, as leaves applied to the springs, after the usual manneragainst either rate risk of breakage.

face of the metal,wherever desirable, to obvi- When several sets ofsprings are used to one hub, they may be arranged to break jointsomewhat after the manner shown in Fig. 8. When round metal, as wire, isused for the springs and they are formed double, a coil, as shown inFig. 7 at H, is formed therein. The springs can be single, as one-halfof Fig. 4t, and joined together as there shown or without joining, asdesired. The springs may also be made each with two coils after themanner shown in Fig. G, and two springs may be joined after the mannerillustrated in said figure.

What I claim as new, and desire to secure by Letters Patent, is-

l. A Wheel for bicycles and other vehicles formed with a centralaxle-hub, having a set of eccentrically-coiled springs arranged atintervals in radiating lines therefrom, and resiliently connecting itwith an encircling spoke-nave with which the interior ends of rigidspokes engage, essentially as set forth.

2. A wheel for bicycles and other Vehicles, having a set of binarysprings, each formed with two eccentric coils as termini and connectingthe axle-hub resiliently with a special spoke-nave encircling it, andforming the center of a system of rigid spokes extending therefrom tothe rim of the Wheel, essentially as set forth.

. 3. Ina wheel for bicycles and other Vehicles, between its axle-hub andan encircling spokenave, double sets of binary springs, each of which isformed with ends coiled eccentrically, and its midway web folded,essentially as set forth.

4. A wheel for bicycles and other vehicles, having an axle -hubresiliently suspended within an encircling spoke-nave, by a system ofbinary springs eccentrically coiled toward each end of its web, securedto a spindle of the spoke-nave at the center of each coil, and eachengaging by a midway bend or fold with a spindle securing it to theaxle-hub, essentially as set forth.

5. In a wheel for` bicycles and other vehicles, the combinationconsisting of-iirst; an axlehub formed with a flange at each end,between which extend spindles parallel vto the axle-hub, arranged atintervals around the same-second; a spoke-nave formed as two cheeks ordisks, encircling the axle-hub and united by cross-rods or spindles atintervals, and-third; double sets of binary springs, each havingeccentricallyfcoiled ends engaging with spindles of the spoke-nave, andeach formed with a U-shapedV midway bend, engaging with a spindle of theaxle-hub, essentially as set forth.
